Description

  The present invention realizes QoS control for each service flow without increasing complexity compared to the existing QoS control method for each bearer, and enables QoS control for a new service flow generated according to the service request, thereby enabling the service request. It relates to a plan for improving the response time to.

  In a mobile communication system, a QoS (Quality Of Service) level varies depending on a media type of an application service used by a terminal device (user), and QoS is transmitted while guaranteeing a QoS level suitable for the media type at the time of packet transmission of the application service. Provide control.

  In this connection, the QoS control method provided in the LTE network is a QoS control method in units of EPS Bearer (hereinafter, bearer).

  In the LTE network, in order for a terminal device (user) to use an application service, an EPS Bearer (bearer) for data transmission is generated.

  Such a bearer passes through a wireless section connecting the terminal apparatus and the base station apparatus, and a wired section connecting the base station apparatus, the S-GW and the P-GW, and then the terminal apparatus and the P- It can be said that it is a tunnel (wireless section + wired section) generated between the GW.

  The data of the terminal device is transmitted in the form of an IP-based packet through this tunnel or bearer, and the traffic flow by the packet transmission is called a service flow.

  Until now, since the types of application services provided to terminal devices were relatively limited, QoS control on a bearer basis applying QoS in a logical unit called “bearer” by combining several types of services. The method was used.

  Therefore, the existing QoS control method for each bearer defines the QoS level (QoS parameter) for each bearer and guarantees (applies) the QoS for each bearer. Therefore, all service flows transmitted through one bearer are the same. The QoS (bearer QoS level) is applied and transmitted.

  In the end, the existing QoS control method per bearer has the advantage that the complexity of QoS control can be reduced, but it is not possible to apply differential QoS to service flows belonging to one bearer. There is a limit.

  These limitations may not be a major problem in situations where the types of application services are relatively limited, but the current or future situation where various types of application services are rapidly developing / appearing (Example: 5G) is a problem that must be improved.

  Therefore, the present invention realizes QoS control for each service flow that enables more differential QoS application without increasing complexity compared to the existing QoS control method for each bearer, and particularly for service requests. It is possible to improve the response time for a service request by enabling priority processing for.

FIG. 5 is a flowchart illustrating a QoS control method for a service request according to an embodiment of the present invention. FIG. 5 is a flowchart for explaining a QoS control method using an application identification code according to an embodiment of the present invention. It is a block diagram for demonstrating the structure of the terminal device by one Example of this invention. It is a block diagram for demonstrating the structure of the base station apparatus by one Example of this invention.

  In the QoS control method proposed in the present invention, the following effects can be derived.

  That is, according to the present invention, application services having different service requirements can be provided with different QoS by dividing the unit for controlling QoS into service flow units instead of existing bearers. In realizing QoS control on a per-flow basis, it is an advantageous effect that control signaling can be minimized through a reactive QoS control scheme in which QoS parameters applied to the downlink are directly applied to the uplink.

  In addition, according to the present invention, in the above-described reactive QoS control scheme, the response time for the service request can be improved by realizing the QoS control for the uplink corresponding to the initial service request for which the QoS control was impossible. In addition, the application identification information necessary for the QoS control of the initial service request is replaced with a short length (small size) identification code to maximize the resource utilization efficiency and the QoS control policy is externally applied. It is an effect that attracts attention because it can be prevented from being exposed to light.

  In the following, a QoS control method for each service flow proposed in the present invention with reference to the accompanying drawings, an apparatus and a configuration for realizing the QoS control method will be described, and the above-described effects achieved in the process will be more specifically described. explain.

  In describing an embodiment of the present invention, a 4G (LTE / EPC) system or a 5G (Next Generation) system is targeted, but the main gist of the present invention is not limited to a specific communication system. The present invention can also be applied to a normal system having a similar configuration. In addition, the steps constituting the embodiment of the present invention may be executed with their order changed or with some steps omitted.

  First, an operation flow when realizing QoS control in units of service flows through the reactive QoS control method according to an embodiment of the present invention will be described with reference to FIG.

  First, the terminal device 10 transmits a service request to the service server 50 to receive provision of a new service in step ‘S10’.

  The service request message at this time is a message generated in the application layer (Application Layer) and transmitted to the user plane (User Plane), and generally uses HTTP or SIP protocol.

  Next, the service server 50 transmits information for setting a policy for the service to the core network 30 in response to a service request from the terminal 10 in step ‘S20’.

  The message at this time includes, for example, the name of the service (PDU name), information on the necessity of continuity of the session (Continuity flag), and information on the service flow (Flow descriptor, eg: IP address, port, QoS control information) ) Can be included.

  Next, the core network 30 determines whether or not it is necessary to set (generate) a new session (PDU session) with the terminal device 10 based on the information received from the service server 50 in step 'S30'. to decide.

  When it is determined that a new session needs to be generated, the core network 30 performs a process for setting a session with the terminal device 10 in step ‘S40’.

  At this time, the core network 30 transmits to the terminal device 10 and the base station device 20 whether session continuity is supported.

  Here, the terminal apparatus 10 and the base station apparatus 20 perform different operations depending on whether or not session continuity is supported.

  When the continuity of the session is not necessary, the terminal apparatus 10 and the base station apparatus 20 prepare for the case where the connected cell (Cell) is changed while the session is established (Established) and the service is in progress. The operation, that is, the operation for handover is not performed.

  The operation for the handover includes a measurement setting and reporting process in which the terminal device 10 periodically measures the signal strength of the surrounding cells and reports the signal strength to the base station.

  On the contrary, when session continuity is necessary, the terminal apparatus 10 and the base station apparatus 20 perform an operation for a case where a connected cell (Cell) is changed, that is, an operation for handover.

  Accordingly, the terminal device 10, the base station device 20, and the core network 30 process the remaining process for session setting in step ‘S50’.

  When the session setting is completed, the core network 30 informs the service server 50 that the session setting is completed in step ‘S60’.

  Accordingly, the service server 50 transmits the service traffic, that is, the downlink packet, to the core network 30 through step 'S70'.

  The core network 30 that receives the downlink packet includes the QoS control information in the header of the downlink packet (marking) and transmits it to the terminal apparatus 10 and the base station apparatus 20 in step ‘S80’.

  At this time, the QoS parameter confirmed from the QoS control information is a value indicating the priority order of the packet service flow, and the base station apparatus performs scheduling and resource allocation for the downlink packet based on such a QoS parameter.

  Thereafter, the terminal device 10 and the base station device 20 utilize the QoS control information included in the header of the downlink packet in steps 'S90' and 'S100', and thereafter uplink in the same service flow. By applying the same QoS parameter as that of the downlink packet to the packet, the uplink grant is processed with the same priority.

  As described above, according to the reactive QoS control method according to an embodiment of the present invention, the QoS control for each service flow is realized, and the QoS parameter applied to the downlink is applied to the uplink as it is. Can be confirmed to be minimized.

  By the way, according to the reactive QoS control method described above with reference to FIG. 1, it is possible to confirm that there is no applicable QoS control information for the service request in step 'S10'. .

  Thus, the absence of QoS control information applicable to a service request means that QoS control for an uplink packet corresponding to the initial service request is impossible.

  In other words, the reactive QoS control method is a method in which QoS is applied to uplink packets belonging to the same service flow when one or more downlink packets occur. In the case of a service in which a downlink packet is generated (generally, UE-initiated service or Mobile Originating Service), there is QoS information that can be applied to the first uplink packet that the terminal device sends for the service request. I do not.

  If there is no QoS information applicable to the first uplink packet (service request message) sent by the terminal device for service request, and uplink packet transmission is processed with a lower priority than other packets, The request message cannot be transmitted for a long period of time, and there is a problem that the service quality felt by the user is degraded.

  In order to solve such a problem, in the QoS control method for each service flow according to the present invention, the QoS control information can be applied to a service flow newly generated for a service request in the terminal device 10. Suggest a plan.

  That is, in the QoS control method for each service flow according to the present invention, the QoS control information that can be unconditionally applied to the new service flow by the core network 30 during the session setting process between the terminal device 10 and the core network 30 This is transmitted to the station device 20.

  Therefore, in the terminal apparatus 10 and the base station apparatus 20 that have received the QoS control information that can be applied unconditionally to the new service flow, when a new service flow occurs, the QoS control information received from the core network is used to The uplink grant requested from the terminal device 10 is generated by the flow.

  Here, processing the uplink grant can be understood as that the base station apparatus 20 performs scheduling and resource allocation for the uplink packet requested to be transmitted from the terminal apparatus 10.

  However, when QoS control information is unconditionally applied to a new service flow in this way, QoS control for uplink packets is possible, but the limitation that QoS control such as difference between service flows becomes impossible is possible. Can predict points.

  Even for a new service flow, a service flow for a specific application may have a relatively high priority of service requests.

  For example, when the grade is high according to the application service subscription information, or when the importance of the application service is high (eg, emergency / disaster safety situation), the priority may be high depending on the choice of the operator.

  Therefore, in order to solve such a limit point, an embodiment of the present invention additionally proposes a method capable of processing a service request generated in the terminal 10 according to priority.

  The operation flow in the QoS control method for service requests according to an embodiment of the present invention will be described with reference to FIG.

  First, the terminal device 10 acquires QoS control information for a new service flow from the core network 30 in a session setting process with the core network 30 through steps ‘S110’ and ‘S120’.

  Accordingly, the terminal device 10 stores the received (acquired) QoS control information in step ‘S130’.

  The QoS control information at this time may include at least one of the application identification information (APP ID) and the application grade confirmed by the application identification information (APP ID).

  Here, the application identification information is a value uniquely given to each application in the OS or the platform, and the grade of the application is related to the priority order of the service request for each application.

  Then, if a service flow for uplink packet transmission of a specific application is newly generated in step 'S140', the terminal apparatus 10 applies the stored QoS control information to the base station apparatus 30 to generate an uplink grant. Request.

  At this time, the terminal device 10 identifies the specific application in which the service flow has occurred and transmits the identification information of the specific application to the base station device 20 or bases the grade of the application confirmed by the identification information of the specific application. By transmitting to the station apparatus 20, an uplink grant can be requested.

  For reference, when a specific application in which a service flow has occurred is identified, the terminal apparatus 10 requests the uplink grant from the base station apparatus 20 in the priority order according to the application class confirmed by the identification information of the specific application. You can also

  On the other hand, when the identification information of the specific application is received from the terminal device 10 in steps 'S150' and 'S160', the base station apparatus 20 gives priority based on the application class confirmed by the identification information of the specific application. Uplink grants can be processed based on rank.

  Alternatively, the base station apparatus 20 may process the uplink grant with the priority according to the grade of the specific application received from the terminal apparatus 10 through steps ‘S150’ and ‘S160’.

  Here, in order for the base station apparatus 20 to process the uplink grant based on the priority order according to the application class confirmed by the identification information of the specific application received from the terminal apparatus 10, the application identification information (APP ID ) And the QoS control information including the grade of the application confirmed by the application identification information (APP ID) must be stored in the base station device 20 already.

  As described above, according to the QoS control method for a service request according to an embodiment of the present invention, even if a new service flow is used, the uplink grant is processed according to the priority of each application determined by the QoS control information. QoS control such as a difference between service flows becomes possible.

  Meanwhile, in the above description with reference to FIG. 2, the terminal apparatus 10 has been described as transmitting the identification information of the specific application or the grade of the specific application to the base station apparatus 20 when the uplink grant is requested in step ‘S140’.

  However, whenever the uplink grant is requested in this way, the identification information itself of the application having a long length (large size) is directly transmitted to the base station apparatus 20 in some cases, the loss of control may be large.

  In addition, when the application grade is directly transmitted to the terminal device 10, the application grade may leak to the outside, and when the terminal device 10 is hacked / modulated, the actually lower grade application is high. It can also be anticipated that there may be a demand for uplink grants that are modulated to grade applications.

Therefore, in one embodiment of the present invention, in order to solve the above-mentioned limit point, for example, the identification information of the application is set to a code value (short length) within a critical size through a mapping table as shown in (Table 1) below. We propose an additional method that uses application identification codes, which are replaced codes.

  The application identification code according to the present embodiment has a shorter length than the application identification information, and the application identification information and the identification code may have a relationship of 1: 1 or N: 1. .

In the latter case, two or more pieces of application identification information correspond to one identification code, and at this time, the two applications have equivalent uplink classes.

  On the other hand, the relationship between the application identification information and the identification code may be configured with explicit mapping information as in the mapping table or may be defined as a hash function.

  For example, if a hash function is defined as F (x) and x is an input value (application identification information), an output value (identification code) Y = F (x) can be obtained.

  The operation flow in the QoS control method using the application identification code according to an embodiment of the present invention will be described with reference to FIG.

  First, the terminal device 10 acquires QoS control information for a new service flow from the core network 30 in a session setting process with the core network 30 through steps ‘S210’ and ‘S220’.

  As described above, the QoS control information acquired by the terminal device 10 includes, for example, a mapping table or a hash function that can replace application identification information (APP ID) with an identification code.

  At this time, the base station device 20 obtains QoS control information for the new service flow from the core network 30 through step 'S230'. The QoS control information obtained by the base station device 20 in this way includes, for example, Application identification codes and application grades identified by each identification code can be included.

  Further, when the service flow for uplink packet transmission of the specific application is newly generated in step 'S240', the terminal device 10 identifies the specific application and is identified with reference to the mapping table or the hash function. The identification code replacing the identification information of the specific application is confirmed.

  Thereafter, the terminal apparatus 10 transmits an uplink grant request including the replacement / confirmed identification code to the base station apparatus 20 in step ‘S250’.

  The base station device 20 that has received this confirms the grade of the specific application corresponding to the identification code received from the terminal device 10 in steps 'S260' and 'S270', and the priority order based on the confirmed application grade. The uplink grant will be processed based on

  As described above, according to the QoS control method using the identification code according to the embodiment of the present invention, the uplink grant is processed according to the priority order for each application determined by the QoS control information, and thus, there is a difference between service flows. It is possible to maximize resource utilization efficiency by replacing the application identification information necessary for QoS control of the initial service request with an identification code of a short length (small size), It is possible to prevent the QoS control policy from being exposed to the outside by not transmitting the application grade to the terminal device 10.

  Hereinafter, the configuration of the device that realizes the QoS control method for each service flow proposed in the embodiment of the present invention, that is, the configuration of the terminal device 10 and the base station device 20 will be described in detail.

  Prior to a specific description, the QoS control information according to an embodiment of the present invention is included in a QoS control information for processing a new service flow generated according to a service request and a downlink header according to a reactive QoS control scheme. It can be divided into QoS control information (to be marked).

  However, in the following, for convenience of explanation, the former (QoS control information for processing a new service flow) is referred to as “first QoS control information”, and the latter (included (marked) in the downlink header). (QoS control information) will be referred to as “second QoS control information”.

  First, FIG. 4 shows the configuration of the terminal device 10 according to an embodiment of the present invention.

  As illustrated in FIG. 4, the terminal device 10 according to an embodiment of the present invention includes an acquisition unit 11 that acquires first QoS control information, a confirmation unit 12 that confirms an identification code from the first QoS control information, and an uplink. A configuration including a transmission unit 13 for transmitting a grant request can be provided.

  In addition to the above-described configuration, the terminal device 10 according to an embodiment of the present invention may have a configuration that further includes a processing unit 14 that processes the second QoS control information.

  The entire configuration or at least a part of the configuration of the terminal device 10 including the acquisition unit 11, the confirmation unit 12, the transmission unit 13, and the processing unit 14 is implemented by a software module or a hardware module, or a software module and a hardware module. It can be implemented in combination with a wear module.

  Here, the software module can be understood as, for example, an instruction word executed by a processor that performs an operation in the terminal device 10, and such an instruction word is mounted on a memory in the terminal device 10. Can have a form.

  After all, the terminal device 10 according to an embodiment of the present invention enables QoS control in service flow units through the above configuration. Below, it demonstrates more concretely about each structure in the terminal device 10 for this.

  The acquisition unit 11 performs a function of acquiring the first QoS control information.

  More specifically, the acquisition unit 11 acquires the first QoS control information from the core network 30 by setting a session with the core network 30.

  Thus, the first QoS control information acquired from the core network 30 includes a mapping table or a hash function that can replace the identification information of each application with the identification code.

  At this time, the base station apparatus 20 also acquires first QoS control information for QoS control of the new service flow from the core network 30.

  As described above, the QoS control information acquired by the base station apparatus 20 can include an application identification code and an application grade confirmed by each identification code.

  The confirmation unit 12 performs a function of confirming the application identification code.

  More specifically, when a service flow for uplink packet transmission of a specific application is newly generated, the confirmation unit 12 identifies the specific application that has generated the service flow, and the mapping table or hash function in the first QoS The identification code replaced with the identification information of the specific application identified with reference to is confirmed.

  The transmission unit 13 performs a function of transmitting an uplink grant request.

  More specifically, when the identification code of the specific application that newly generated the service flow is confirmed, the transmission unit 13 transmits an uplink grant request including the confirmed identification code to the base station apparatus 20 to be uploaded. Requests scheduling and resource allocation for link packet transmission.

  On the other hand, the base station device 20 confirms the grade of the specific application corresponding to the identification code received from the terminal device 10 in accordance with the uplink grant request, and assigns the uplink grant with the priority according to the confirmed grade. Process.

  The processing unit 14 performs a function of processing the second QoS control information.

  More specifically, when the second QoS control information is acquired from the header of the downlink packet received from the base station apparatus 20 in the same service flow after the uplink packet transmission by the uplink grant process, By applying the specific QoS parameter confirmed from the acquired second QoS control information to the service flow, the uplink packet in the subsequent service flow is transmitted with the QoS based on the specific QoS parameter.

  That is, the processing unit 14 applies the same QoS parameter as that of the downlink packet to the uplink packet in the same service flow by using the second QoS control information included in the header of the downlink packet. Thus, the uplink grant can be processed with the same priority.

  At this time, the acquisition unit 11 assists in acquiring the second QoS control information from the header of the downlink packet received from the base station apparatus 20, and the confirmation unit 12 is also applied to the downlink packet from the second QoS control information. Of course, it helps to identify specific QoS parameters.

  As described above, the terminal apparatus 10 according to an embodiment of the present invention processes the uplink grant according to the priority of each application for the newly generated service flow, and thereafter the same service flow. By applying the same QoS parameter as that of the downlink packet to the uplink packet in the uplink packet, an uplink grant is processed with the same priority.

  Therefore, the terminal device 10 of the present invention enables QoS control for each service flow without increasing complexity compared with the existing QoS control method for bearers, and is necessary for QoS control for an initial service request. Resource utilization efficiency can be maximized by replacing the application identification information with an identification code having a short length (small size).

  Hereinafter, the configuration of the base station apparatus 20 according to an embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 5, the base station apparatus 20 according to an embodiment of the present invention receives an uplink grant request and second QoS control information from the acquisition unit 21 that acquires the first QoS control information, and the terminal apparatus 10. It can have a configuration including a processing unit 22 for processing.

  The entire configuration or at least a part of the configuration of the base station apparatus 20 including the acquisition unit 21 and the processing unit 22 is implemented by a software module or a hardware module, or a combination form of a software module and a hardware module. Can be done.

  Here, the software module can be understood as, for example, an instruction word executed by a processor that performs an operation in the base station apparatus 20, and such an instruction word is installed in a memory in the base station apparatus 20. Can have a modified form.

  After all, the base station apparatus 20 according to an embodiment of the present invention enables QoS control for each service flow through the above-described configuration. Hereinafter, each configuration in the base station apparatus 20 for this purpose will be described more specifically.

  The acquisition unit 21 performs a function of acquiring the first QoS control information.

  More specifically, the acquisition unit 21 acquires the first QoS control information from the core network 30 by setting a session between the terminal device 10 and the core network 30 in the terminal device 10.

  As described above, the first QoS control information acquired from the core network 30 may include the application identification code replaced from the application identification information and the grade of the application confirmed by each identification code.

  At this time, the terminal device 10 also acquires the first QoS control information for QoS control of the new service flow from the core network 30.

  Thus, the QoS control information acquired by the terminal device 10 can include a mapping table or a hash function that can replace the application identification information with an application identification code of a short length (small size).

  The processing unit 22 performs a function of processing the uplink grant request.

  More specifically, the processing unit 22 generates a service flow for uplink packet transmission of a specific application in the terminal device 10, thereby causing the terminal device 10 to confirm the specific application from the first QoS control information. When an uplink grant request including an identification code is received, the uplink grant is processed based on the priority according to the application class confirmed by the identification code of the specific application in the first QoS control information. It will be.

  At this time, when a service flow for uplink packet transmission of a specific application is newly generated, the terminal device 10 identifies the specific application that generated the service flow and refers to the mapping table or hash function in the first QoS. By confirming the identification code replacing the identification information of the specific application identified in this way, and transmitting an uplink grant request including the confirmed identification code to the base station apparatus 20, scheduling for uplink packet transmission and Request resource allocation.

  Further, the processing unit 22 performs a function of processing the second QoS control information.

  More specifically, the processing unit 22 acquires the second QoS control information from the header of the downlink packet received from the core network 30 in the same service flow after the uplink packet transmission by the uplink grant process. By applying the specific QoS parameter confirmed from the second QoS control information, to the service flow, the downlink packet is processed to be transmitted to the terminal device with the QoS based on the specific QoS parameter.

  At this time, the processing unit 22 includes the second QoS control information in the header of the downlink packet transmitted to the terminal apparatus 10, and the terminal apparatus 10 that has received the second QoS control information when transmitting the uplink packet in the same service flow. An uplink packet can be transmitted with the same QoS as that of the downlink packet by a specific QoS parameter confirmed from the control information.

  That is, the processing unit 22 applies the same QoS parameter as that of the downlink packet to the uplink packet in the same service flow by using the second QoS control information included in the header of the downlink packet. Thus, the uplink grant can be processed with the same priority.

  As described above, the base station apparatus 20 according to an embodiment of the present invention allows the uplink grant to be processed according to the priority of each application for a newly generated service flow. By applying the same QoS parameter as that of the downlink packet to the uplink packet in the flow, the uplink grant is processed with the same priority.

  Therefore, the base station apparatus 20 of the present invention enables QoS control for each service flow without increasing complexity compared with the existing QoS control method for bearers, and is necessary for QoS control for an initial service request. Resource utilization efficiency can be maximized by replacing the application identification information with an identification code having a short length (small size).

  In the present invention, it is possible to prevent the QoS control policy from being exposed to the outside by not transmitting the application grade to the terminal device 10.
